Multipurpose IoT Hub
One modular device covering a wide range of IoT applications. CHESTER is used to data telemetry data of the connected systems, monitoring of a large variety of sensors, remote control and location tracking.
Communication to the internet from most distant places. CHESTER communicates through LPWAN technologies, such as NB-IoT or LoRaWAN, even from places where regular internet connectivity is not available.
Low power consumption
The device features low power consumption and offers a reliable operation from a battery for up to 10 years. CHESTER can operate in outdoor and dusty environments.
Ready for integration
CHESTER can by easy connected to the cloud, mobile applications and other services, such as Azure IoT Hub, Grafana, Ubidots or Blynk as well as it can be integrated with your endpoint through the REST API and Webhooks.
